Can I get download statistics for private npm packages?

No, this skill currently only retrieves data for public packages available on the official npm registry.

How accurate and up-to-date is the download data?

The data is sourced directly from the npm API, but typically has a 24-48 hour delay due to the registry's aggregation process.

Why is there a cache for download statistics?

Historical download data doesn't change once recorded; a 24-hour cache ensures faster response times for Claude while keeping the data sufficiently fresh.

What counts as a 'download' in these statistics?

The count includes all requests that result in a package tarball being served, which covers npm installs, CI/CD builds, and mirror synchronization.

Does this skill support custom date ranges?

Yes, you can specify a custom period using the YYYY-MM-DD:YYYY-MM-DD format to analyze specific historical timeframes.
